I discovered this issue on x86 on linux 2.6.8/9 which led Linus to
fixing by 2.6.11. Andi Kleen has not ported the patch to x86-64 from
what I know, so wine will still suffer under it -- ie single stepping
into signal handlers, see mailing list archives. You need to get your
kernel patched to fix the problem. I have access to x86-64 systems
now and may be able to help.
